天津市人民医院1980-2009年结直肠癌患者病例资料分析

Case Analysis of the Rectal Cancer Patients Admitted in Tianjin Union Medicine Centre from 1980 to 2009 yr

为探讨结直肠癌的发病情况、病理特点及手术方式的变迁情况，本研究统计天津市人民医院1980-2009年收治的结直肠癌病例，共7585例，对其性别、年龄、肿瘤部位、病理特点及手术方式等进行分析。结果显示，结直肠癌住院人数逐年递增；中位发病年龄由19801984年的52．0岁上升至2005-2009年的84．0岁；青年人（（40岁）结直肠癌比例由1980～1984年的18．9％下降至2005～2009年的3．1％；直肠癌比例由89．5％降至65．7％，结肠癌比例由10．5%升至34．3％；病理类型仍以腺癌为主（87．5％）；从术式选择分析，直肠癌前切除术所占比例显著上升（由19．3％升至37．2％），Miles术比例下降（由66．8％降至24．3％）。结果表明，结直肠癌患者逐年增加，发病年龄趋于老龄化，病理类型以腺癌为主，发病部位仍以直肠为主，但所占比例逐年下降，保肛手术比例逐年扩大。

In order to explore the incidence status,pathologic features and evolution of procedures,authors analysed the sex, age, neoplasms sites, pathological features and procedures, etc of 7585 cases with colorec-tal cancer admitted in Tianjin Union Medicine Centre from 1980 to 2009 yr. in this study. As results,admit-ted case numbers increased year by year,mid-invasive age of 52.0 yr. during 1980-1984 yr. was up to 64. 0 yr. during 2005-2009 yr; young persons（〈40 yr. ）suffered from colorectal cancer decreased from 18. 9% （1980-1984 yr. ） to 3.1%（2005-2009 yr. ） ;the ratio of rectal cancer reduced from 89.5% to 65.7% ,the ra- tio of colonic cancer up from 10.5 % to 34.3 % ;adenocarcinoma was predominant in pathological pattern （87.5%） ;in choice of procedures,anterior resection for rectal cancer accounted from 19.3% to 37.2% ,ap-peared significant up,while Miles procedure dropped from 66.8% to 24.3%. Results show that the num-bers of colorectal cancer patients increase year by year;invasive age trends to aging;adenocarcinoma is pre-dominant in pathological pattern;rectum is still main invasive site, but the ratio is down year by year,and the ratio for preserving-anus procedure enhances year by year.
